It is known as transient paresthesia when sensation is temporarily abnormal.
Cultural references[edit | edit source]
Saturday night palsy is a colloquial term for it.
Presentation[edit | edit source]
Symptoms vary depending on the severity and location of the trauma; however, common symptoms include wrist drop (the inability to extend the wrist upward when the hand is palm down); numbness of the back of the hand and wrist; and inability to voluntarily straighten the fingers.
Causes[edit | edit source]
There are many ways to acquire radial neuropathy.
The term Saturday Night Palsy refers to nerve damage that can occur if a drunk person falls asleep with the back of their arms compressed by a bar edge, bench back, or like object. Radial neuropathy is also called honeymooners palsy, since it can be acquired by sitting with an arm draped over the back of a neighboring chair (or movie-theater seat) for a long time.
Both Saturday night palsy and honeymooners palsy refer to the fact that the nerve damage is generally forewarned by arm pain to a degree that only excessive love or liquor would drive a person to keep their arm in such an uncomfortable position.
Breaking the humerus and deep puncture wounds can also cause the condition.
Improperly sitting in a chair for several hours such that the armrest compresses the underside of the forearm is another potential cause.
Prognosis[edit | edit source]
Radial neuropathy is not necessarily permanent. Peripheral nerve regeneration is an imperfect and slow process, and full restoration of ability may take months, years, or may never occur.
